Answer:
water at 0C
Explanation:
The colder the water is, the denser it is, so the water here with the lowest temperature, is 0C
We know, It's atomic formula = C4H10
Now, we know molar mass of C = 12 & H=1
so, it would be: 12*4+1*10 = 48+10 = 58
The purpose is that it shows you all the elements we know and it arranges them in groups that are also the same kind like Chemistry.
How strong the bonds are between the atoms
